Exelent choice no more hinging cables
I recently purchased the EZ Outlet Electrical Outlet Extender, and it has been a total game-changer for my home. I have a few outlets behind furniture and in tight corners that are almost impossible to use, and this product solved that problem instantly. The extender itself feels very sturdy and well-made. The most useful feature is the flexible, gooseneck-like arm that lets you bend the outlet away from the wall. This allowed me to easily plug in my lamp and a few other devices that were previously unreachable. I also love the extra ports. The two regular AC outlets, a USB-A port, and a USB-C port are incredibly convenient. It's great to be able to charge my phone and my laptop from the same spot without needing a separate charging block. The USB-C port is particularly fast, which is a huge bonus. Setup was as easy as plugging it in. There's no complicated wiring or anything to deal with. It's a simple, elegant solution that works exactly as advertised. If you have any hard-to-reach outlets in your home, I highly recommend this product. It's well worth the investment.

Looks good, adjustability is super nice
This is attractive (for what it is) and is working well, I really like the adjustability - the only downside so far is that the USB ports are on the underside where I'm using it, so are basically unusable on a regular basis unless you want to leave a cable dangling from it, tho if you had it run up or to the right from the outlet, that wouldn't be a factor.

I absolutely love this! It’s a life changer for me as I’m always pulling the cord out from the wall in the attempt to stretch it. This now sits plug now sits perfectly between my bed and the wall. Excellent quality, easy to plug in and makes my life easier!

Nice length and looks good
Bought two different types/brands of outlet extenders, overall I like this better out of the two when it comes to looks and functionality. This one you plug it in then rotate the outlet to the spot you need. One adhesive pad holds it in place easily due to light weight and trim materials. You can still plug something else in the wall outlet, this only takes up one of the outlets. It would be great if they added usb plugs to this like the other one.
